Claims.

My invention relates to apparatus for and methods of perforating, as for punching, and. more particularly relates to novel apparatus for and methods of manufacturing thumb cuts in one 5 or more continuous strips of material used for manufacturing bags or like containers which have a parallel shear cut off at the open end.

In the continuous process for manufacturing paper bags, the strip of material is intermittently brought to a stop for the purpose of cutting the strip to the proper length in accordance with the desired size of the bag.

An object of my invention is to provide novel apparatus for and methods of making cuts at various positions in a material.

Another object of my invention is to provide novel apparatus for and methods of making thumb cuts at the time that the continuous strip is stopped.

Still a further object of my invention is to provide novel apparatus for and methods of making thumb cuts at variable distances from the shearing point of a continuous strip of material.

There are other objects of my invention which, together with the foregoing will appear in the detailed description which is to follow in connection with the drawings in which:

Figure 1 is a side elevation of the assembled unit.

Figure 1a is a schematic assembly view of the 3 thumb cut machine and the bag machine.

Figure 2 is a cross section through A-A of Figure 1.

Figure 3 is a cross section taken through 3-3 of Figure 2.

Figure 4 is a cross section through CC of Figure 1. V

Figure 5 is a detailed view of Figure 1 showing part of the assembled unit with parts cut away to show the cutting position of the punch.

Figure 6 is a. detailed view of the grooved bar of Figure 1.

Figure '7 is a detail of the driven gear cam roller and lever arm of Figure 1,

Figure 8 is a top plan detail of the dovetail shaped punch slide and housing of Figure 1.

Figure 9 is a cross section of the punch holder and its clamping parts.

Referring to Figures 1 and 7, a bevelled gear 1, preferably having a one to one ratio with its engaging gear of the bag-making machine (not shown) from which it derives its power, is mounted on a rotating shaft 3 by set screws 2. Revolving shaft 3 driven through bevelled gear 1, is held in place by suitable bearings 4 on frame 5.

Cam 6 (Figure 7) is securely fastened to, by set screws 7, and revolves with, shaft 3. By loosening set screws '7, the cam 6 can be adjusted so as to be angularly placed with respect to shaft 3 to properly position it during operations.

Revolving on the surface of cam 6 is a cam roller 8 which is secured by means of stud 9 to the lever 10. Stud 9 passes through an elongated hole 11 in lever 10. This permits proper operating adjustments to be made of the cam follower 8 5 with respect to cam 6 to allow for wear and grinding of the punch to be described. Cam follower 8 is moved down in hole 11 towards cam 6 when a new punch is used and is moved upwards in hole 11 away from cam 6 as the punch is worn. 7 Lever 10 is held in position on the frame 5 by stud 12 upon which it oscillates as cam follower 8 moves over the surface of cam 6. Fastened to lever 10 by means of stud 12, is the lever 13 which is attached to one end of the grooved bar 14 by a stud 1-5.

The opposite end of grooved bar 14 is connected by means of a stud 17 to lever 16. Lever 16 is held in place on frame 5 by means of a stud 18. The end of a spring 19 is connected by stud 20 to lever 16.; The opposite end of spring 19 is connected to the frame 5 on the stud 21. Spring 19 creates a tension against the forward oscillation of lever 16.

As cam follower 8 moves along the cam 6, lever 10 is oscillated about pin 12 and in turn oscillates lever 13. The oscillations of lever 13 in turn impart a sidewise and arcuate motion to bar 14 about pins 12 and 18 as pivots.

Spring 19, acting on the entire mechanism thus far described, through lever 16, tends to hold lever 16 in one extreme position from which it is rocked in a counter-clockwise direction. The action of the spring is transmitted through lever 16, to bar 14, lever 13, and lever 10 to the follower 8 95 which is thus kept always bearing against and therefore always in engagement with the earn 6.

As, therefore, the cam 6 rotates and the follower 8 is moved for example from a point nearest the center of shaft 3 at the small part of the cam, as 100 illustrated in Figure 5, to a point furthermost from the center of shaft 3 at the large part of the cam, as illustrated in Figure 1, lever 16 is rocked about pin 12 in a counter-clockwise direction against the actions of spring 19. This in turn 105 rocks lever 13 in a counter-clockwise direction about pin 12. Pin 15 describes an arc in a counter-clockwise direction about pin 12 and in doing so carries rod 14 in a similar path. Rod 14 in turn, through pin 17, rocks lever 16 about pin 18 n full length of bar 14. In this channel there rides a roller 22 attached by means of stud 23 to the lower end of lever 24. The upper end of lever 24 I (Figure 2) is connected by set screw part 25 to shaft 26 which is held in place by suitable bearings 27 on housin 26. v

The arcuate motion of the bar 14 has a component which is normal to the longitudinal axis of its channel. This component imparts an arcuate motion to the roller 22 about shaft 26 as the roller moves in the channel. This in turn transmits an oscillating motion to shaft 26.

Attached to shaft 26 by a set screw 29 (Figure 2) is one end of lever 30 (Figure3). The opposite end of lever 30 is provided with an elongated opening 31 through which passes shaft 32. The oscillating motion of shaft 26 oscillates the lever part 30, causing its end, at the opening 31, to move up and down in an arcuate path about shaft 26.

Shaft 32 is held in place by suitable bearings 33 in the punch slide 34 having a dovetail shape as shown in Figure 8. Housing28 encloses punch slide 34 and is fastened, by means of bolts35 (Figure 2) to bed'plate 36. (Figure 3) is held securely in punch slide 34 by means of cap screws 38 passing through punch holder clamp 39 into slide 34. Punch holder 37 is designed to hold punch 40 and the four studs 41. Punch 40 is securely fastened to punch holder 37 by screws 42. Enclosing studs 41 are springs 43. The springs 43 push down the striper 44 which is securely attached to studs 41. This strips the material from punch 40 on its upward motion after it has cut through the material.

The arcuate motions of lever 30 imparts a lever sliding motion through shaft 32 to slide 34 in its guides. Slide 34 in turn, through punch holder 3'7, imparts an up and down or punching movement with respect to bed plate 36, to punch 40 and through studs 41 to stripper 44. The punching motion of punch 40 cuts desired shape of thumb cut as punch 40 passes throughmaterial 45 into die 46.

Die 46 is dovetailed, as shown in Figure 4, and has passing through it a continuous hole of desired shape of punch. Die 46 is securely wedged, due to its dovetail, into a die holder 4'? which has a hole directly under the hole in die 46 to allow cuttings to fall through. Die holder 47 is securely fastened with cap screws 48 to bed plate 36. Bed plate 36 has a hole directly under hole in 4'7 to allow cuttings to fall through, and is securely fastened with cap screws 59 to slide 50. Slide-50 is held in place on frame 5 by guide 51 and rack 52 but free to slide along the direction of the rack 52. Guide 51 is an angle strip which fits into a groove in slide 50 and is held against frame 5 by cap screws 53. Rack 52 is also held against frame 5 by cap screws 54. At one end of slide 50 there is a suitable bearing for shaft 55 on which is mounted a gear 56. Gear 56 meshes with the teeth of rack 52.

The handwheel 57 is attached to shaft 55 by set screws 58 and is used for moving slide 50 with the unit assembled on it to desired location on frame 5'so that thumb cutter is imposition to cut- Punch holder 37 hole in exact location in material 45 for the length of bag required. Slide 50 is thus held in correct position by T bolt 60 which fits into a T slot in frame 5.

In operation, a continuous strip of material for paper manufacture is fed through any well known cutting machine which is driven in timed relation with the shaft 3 through any well known positive drive mechanical connection. The strip of continuous material is, as is well known in the art, intermittently brought to a stop for an interval of time for the purpose of shearing the material to produce bags of predetermined length.

Shaft '3, driven positively from the same source by means of the cam 6, suitably adjusted therein, times the operation of the punch 40 cutting a cut in the strip of continuous material during the time when the material has been brought to a stop as described above.

In order to permit adjustments in the thumb cuts to be made, the rack 52 is provided which permits adjustments of the distance between the cutter and the punch along the path of the strip of material. This permits a number of functions, such for example, as changing the relative position of the thumb cut from the ends or" the bag or compensation for different size of bags to maintain a fixed distance of cut from the ends of the bag.

Figure 1a shows a schematic diagram for carrying out my invention in relation to another machine. Here, the previously described punching machine is shown with bevel gear 1 in engagement with another bevel gear fastened to a shaft. At the end of this shaft, another bevel gear is fastened which in turn engages with another bevel gear which is fastened to a shaft of a shearing machine. A source of mechanical power drives the system as shown, although any other point of application of the power obviously may be used. Provision is thus secured for keeping the mechanisms on the punching machine in syn chronism with the mechanisms on the shearing machine. 7

A continuous strip of material is pulled through in the direction shown in Figure 10. by a suitable mechanism on the shearing machine. At intervals of time, as hereinbefore disclosed, the mate rial is brought to a stop for an interval of time during which the punch in mechanism on the punching machine and the shearing mechanism on the shearing machine operate upon the material.

The distance traveled along the direction of the material in one interval determines the length of material cut off by the shearing machine. Inasmuch as the machines are in fixed relation to each-other, the distance of the line of shearing from the position of punching along the length of the material remains fixed for a given position along the rack ofthe punching mechanism, thus making a fixed location along the direction of travel of the punch cuts with respect to the shearing line in the finished product. By changing the position of the punching mechanism along the rack, which can obviously be done without stopping operations, the position along the direction of travel of the punch out with respect to the line of shear can be changed for a given-length of finished product.

To produce finished products of different length, the intermittent movement of the material is adjusted to the length required and the punchingmechanism adjusted along the rack to properly-position the punch cuts with respect to the line of shear. Thus, in Figure la, I have schematically shown how adjusting the punching mechanism along the direction of travel of the material may be obtained; namely, to allow the positioning of the punch out a whole number of product lengths plus a predetermined definite fraction of a product length.

Although I have disclosed adjustments of the cut from the ends of the bag, it will be obvious that similar adjustment of the thumb out can be obtained transversely to the length of the bag by well known mechanical arrangements using the principle disclosed.

Although I have shown but one punch unit operating on the rack, additional punch units for other operations may be similarly mounted within the scope of my invention. Spring 19, if preferred, may be eliminated and cam follower 8 moved in a cammed slot in cam 6. The cam 6 will then rock lever 13 clockwise and counterclockwise and will operate member 14 in a corresponding manner.

Furthermore, although for purposes of illustration I have shown my invention as adapted to thumb cuts for paper bags, it will be obvious to those skilled in the art that it has numerous other applications, such as for punching operations of all sorts where adjustments of the punch mechanism along the material is desired and where a predetermined time relation in the punching operation is desired, and I do not intend to limit myself by the example of my invention here given except as set forth in the appended claims.
